## Summary description

Proline 36578 is a single-piece ring (box) wrench designed for tightening and loosening fasteners with a closed-end profile. Supplied as one unit per pack, this hand tool is intended for general mechanical and maintenance tasks where a secure grip on bolt or nut heads is required. Suitable for workshop, automotive and household repairs.

## Long description

Proline 36578 is a single-piece closed-end ring (box) wrench engineered for reliable grip and torque transfer when tightening or loosening hexagonal fasteners. Cold-forged and featuring ground heads with a chromium-plated finish, this hand tool offers a smooth contact surface and resistance to wear and corrosion. Supplied as one unit per pack, it is intended for general mechanical and maintenance tasks in workshops, automotive settings and household repairs where a secure, full-contact engagement with bolt or nut heads is required.
Advantages
The cold-forged construction increases strength and durability compared with stamped alternatives, reducing the risk of bending or cracking under load. Precisely ground heads ensure accurate fit on fastener faces to minimise rounding and slippage, while the chromium-plated surface provides corrosion resistance and makes the tool easier to clean. Being a single-piece design, the wrench delivers consistent alignment and reliable torque transfer during repeated use.
Suitable for
 Automotive maintenance and repairs requiring closed-end access to nuts and bolts
 Workshop assembly and disassembly of mechanical components
 Household tasks where a secure grip on hex fasteners is needed
 Periodic maintenance in small industrial settings
Key specifications
 Tool type: single-piece closed-end ring (box) wrench
 Manufacturing: cold forged for enhanced strength
 Heads: ground for precise fit and reduced fastener rounding
 Finish: chromium-plated surface for corrosion resistance
 Supply: one wrench per pack
How to use
Select the appropriate size that matches the fastener head and place the closed-end over the nut or bolt so that all contact points seat evenly. Apply steady force in the intended rotation direction, avoiding sudden jerks that can damage fastener edges. For high-torque situations, ensure correct body positioning and, if necessary, use controlled incremental turns rather than excessive force to prevent tool or fastener damage. After use, wipe the chrome surface clean and store the wrench in a dry toolbox or on a tool rack.
Usage recommendations
Inspect the wrench before each use for signs of wear or deformation; do not use if the head is rounded or cracked. Use the closed-end ring wrench on the correct fastener size to minimise slippage and rounding. Avoid using the wrench with an extension or cheater bar beyond recommended torque limits, and keep the chrome finish clean and dry to prolong service life.
